 * Stop -- called when the plugin instance is to be stopped (e.g. by 
 * displaying another plugin manager window, causing the page containing 
 * the plugin to become removed from the display).
 *
 * Destroy -- called once, before the plugin instance peer is to be 
 * destroyed. This method is used to destroy the plugin instance.
